Open the CIPO recordAbstract From the Canadian patent
Stator designs have wide-mouth slots between adjacent poles. Wire coils with high slot fill conductivity are formed around the poles. In some designs, the wire coils are wave wound around the poles. Thick bar conductors can be used for making the wire coils. The wire coils may be inserted using nozzle dispensers or transferred from a pre-form mandrel. In other designs, the wire coils are pre-formed on transferable pockets that are then mounted on the poles. Optional pole extensions or shoes can be attached to the stator poles after the wire coils are formed around the poles.

Why it's free to use
- Filed May 13, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 13, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 13, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
